Powering T&D sectionalizing switches with photovoltaics: a low cost option

A joint utility-industry project which involved the installation of new, or the rebuilding of existing, transmission and distribution (T&D) sectionalizing switches powered by photovoltaic (PV) applications at a number of electric utilities is documented. The sectionalizing switch project is described, and PV and conventional power supplies for the switches are discussed. Utility switch installations are detailed and project results are given.<
